Principal Fire Safety Engineer

Location: Egremont

Join us in shaping the future of Fire Safety Engineering At RPS Tetra Tech, we're looking for a motivated and ambitious Principal Fire Safety Engineer to join our growing fire safety engineering team.

This role offers the chance to work on a diverse portfolio of projects - delivering fire strategy design and hazard analysis across sectors such as nuclear, residential, commercial, office, waste and recycling and other high-hazard environments. Whether you're actively seeking your next challenge or open to exploring new possibilities, this role offers the chance to grow your career within a consultancy renowned for its technical excellence and collaborative culture.

Purpose & Scope of the Role Within the nuclear sector our projects often involve bespoke, technically complex challenges with limited reference documentation which offers a distinct contrast to the more prescriptive residential sector. Engineers will have the opportunity to apply core fire engineering principles, including modelling and calculations, to deliver innovative, safety-focused solutions. Larger projects may involve developing fire strategies for major new builds, such as regional distribution centres or facilities on nuclear-licensed sites.

You will apply advanced fire engineering expertise in scenarios where standard guidance is limited, using analytical and modelling techniques to develop innovative solutions. This role provides a unique platform to refine and expand the skills that inspire many professionals to pursue a career in fire engineering. As a key member of our consultancy team, you will take responsibility for delivering high-quality fire safety strategies and technical solutions that meet client objectives and regulatory requirements.

Your Impact in this Position In the first year, you will have the opportunity to contribute to complex and innovative fire engineering projects across multiple sectors. The role involves working on high-profile assignments where you will apply your technical expertise in a dynamic and technically challenging environment. Current projects include one of the UK's most significant infrastructure sites, providing exposure to large-scale nuclear work and the chance to develop skills in stakeholder engagement, technical design, and regulatory interaction.

We support career growth through progression toward chartership and access to CIPD-accredited training. For nuclear fire engineering roles, some projects may require understanding the nuclear safety case. While not essential initially, training will be provided to develop this capability. Whether you are seeking your next challenge or exploring new possibilities, this role offers the chance to advance your career within a consultancy recognised for technical excellence and a collaborative culture.

Your Toolkit for Success at Tetra Tech RPS At Tetra Tech RPS we recruit using core capabilities - the toolkit of essential skills, experience, competencies, and responsibilities required to perform the role effectively. As we strive to find the best fit for this position, we are seeking individuals that meet a benchmark level of expertise. But we'll let you in on a secret: there's no such thing as the 'perfect' candidate.

If you feel you meet 75% of the requirements for this role, we would love to hear from you. Fire Safety Engineering Expertise The role involves applying fire safety engineering principles to develop innovative, compliant building designs. You will create fire strategies, conduct hazard analysis and address complex risks. A strong knowledge and understanding of the legislative framework for fire-safe design, including guidance such as Approved Document B, BS 9999 and BS 9991 is essential.

You will bring working knowledge of fire safety engineering principles, including the PD 7974 suite of standards.

Experience with fire modelling software such as CFAST or FDS is advantageous, though not essential, as we provide opportunities to develop these skills. Regulator Interaction You will manage client-facing responsibilities which include attending meetings and conducting site visits to assess existing fire safety measures…
